Lennox · Whole-home indoor air quality
PureAir™ S Purification System
PureAir™ S is the Dave Lennox Signature® Collection air purifier — the top of the range. It senses the air quality in your home, communicates with a compatible Lennox system and the S40 thermostat, and cleans all three classes of contaminants: particles, germs and bioaerosols, and odors and chemical vapors.
Senses, communicates and cleans
PureAir S tracks indoor air quality and ramps the system's fan and its own cleaning stages when the air needs it — for example after cooking, or when outdoor smoke pushes indoor particulate up. Everything reports back through the thermostat and app.
All three classes of contaminants
Hospital-grade media captures fine particles and bioaerosols; photocatalytic oxidation breaks down odors and volatile organic compounds rather than just trapping them. The system produces no ozone and is designed to actively reduce it.
